FORMATION OF TABLE FOR THE FUNCTION
As t represents the temperature in degrees Fahrenheit and c represents the number of cricket chirps per minute.
Considering the function

So
Lets form the data table for this function based on the determined values
PART 1)
Considering the function
As we know that
when
then
- Meaning the number of chirps per minute would increase to , when the temperature t in degrees Fahrenheit increase to 60.
The appropriate logic is that the speed at which cricket chirps is based on the temperature. The table table also indicates that as the temperature t increases, the number of cricket chirps also increases.
PART 2)
- A rate of change is a rate that determines how one quantity changes in relation to another quantity.
Considering the two points
It logically means for every increase of units in (temperature in degrees Fahrenheit), the value of (number of chirps) is increasing to units.
Thus, the rate of change will be .
Part 3)
Considering the function
The data table for this function
Putting in the function brings the value of as .
i.e.
Yes, it does make sense.
Its logical meaning is that at the start, when the value of was temperature in degrees Fahrenheit, then the value of (number of chirps per minute) was .
Given:
Cylinder = radius 2cm ; height 4cm
graduated cylinder = radius 3cm w/ liquid
Volume of a cylinder = π r² h = 3.14 * (2cm)² * 4cm = 50.24 cm³
Volume of a cylinder = Volume of the graduated cylinder
50.24 cm³ = 3.14 * (3cm)² * h
50.24 cm³ = 28.26 cm² * h
50.24 cm³ / 28.26 cm² = h
1.78 cm = h
<span>The liquid rises by 1.78 cm in the graduated cylinder.</span>
Answer:
0.16 can be written with 100 as the denominator.
16/100
To simplify, divide the top and bottom by 4.
4/25
